================
Comment at: clangd/index/Index.h:136
+  // Intern table for strings. Not StringPool as we don't refcount, just insert.
+  llvm::StringSet<llvm::BumpPtrAllocator> Strings;
   llvm::DenseMap<SymbolID, Symbol> Symbols;
----------------
A comment on why we use `BumpPtrAllocator` here might be useful.
I.e., it uses more memory than malloc, but we're getting better data locality. (I hope that I got its intention right)
